THOMAS SPENCER MILLER, OF SOUTH ORANGE, AND JOSEPH H. DICKIXSOX, OFMON'ICLAIR,

To all whom it, may concern:

Be it known that we, THOMAS SPENCER MILLER, a citizen of the UnitedStates, and a resident of South Orange, in ,the county of Essex andState of New Jersey, and JOSEPH H. DioitiNsoN, a citizen ot the UnitedStates, and a resident of Montclair, county of Essex, and State of NewJersey, have invented certain new and useful Im rovements in ConveyiiigApparatus, of which the following is a specication.

O ur invention relates toan improved conveying apparatus of the type einloying a suspended cable as a trackway, an has particular application toimproved means for movang, tightening, raising and lowering the cable.In the present inst-ance, We will describe this apparatus as employed inlogging operations in which a central tower or support is employed, fromwhich a cable is erected radially, and the logs lying near this cableare hoisted and conveyed to any predetermined lace. As soon as the logshave been cleare from a certain run this cable is dropped, and a secondcable is then picked up upon another line extending radially from thecentral su port. Up to the present time, it has been tlie ractice todetach the long portion of the cable from one side of this centralsupport and pick up a second correspending cable; the object in havingtwo cables being to reduce to a minimum the time lost in changing thecable. Hcretofore, however, it has always been the practice to shiftthat portion of the cable, or the main cable extension, running from apoint near the tree support to the back anchorage for the same, afterone of the main cables has been dropped. In the present instance, it isour intention to support the back ortionof the cableway in position, insuc i manner that in shifting from one cable to another we also shiftfrom one inde endent back anchorage to a second. It be noted that if theosition of the main cable be shifted radially in the direction of themovement of the sun, the position of the back anchorage will have acorresponding movement, always, however, exactly opposite tothe maincable, so that in each position of the cable the backward anchorageportion shall be approximately in a straight line with the main cable.

y An important saving of time and labor is Specification of LettersPatent. Application filed May 12, 1905. ,Serial No. 260,187.

thus effected, permitting the cablewayto be in operation more hours perday, and, therefore, to convey a greater iiu-niber of loads whencompared with the cableways as ordinarilyconstructed. .is soon as thecableway is working in one position, the riggers are preparing a backanchorage for the following position. Thus, the operation of thecableway is more continuous 'than heretofore.

Our invention consists in the construction,

combination and arrangement of parts set forth in and falling -withinthe scope of the ap ended claims.

n the accompanying drawings, like characters of reference indicate likeparts in all of the views; and, Figure 1 is a view illus- 70 trating onepreferred embodiment of our apparatus. Fig. 2 is a slightly modifiedform of apparatus, wherein we employ two separate guys in the space of asingle guy forming a, continuation of the main cable 75 extension, asshown in Fig.'1. Fig. 3 is a top plan view of an engine designed foremployment in conjunction with our apparatus; I

certain parts of the engine being omitted;

such view also illustrating the arrangement and construction of drumsfor operating the anchorage. Fig. 4 is a detail View showing the drum,ratchet and pawl mechanism. Referrin now, to' the accompanying drawings,support and B indicates as a whole an engine employed in connection withthe ap aratus. The main cablesvayof the device iss iown at 5, such maincable extending from the head tree to a tail tree or su C is thecarriage of t ie apparatus, and 7 is an out-liaul rope extending fromthe engine drum b throughthe guide-slieave S .at the head tree andthenceacross the carriage to 9 to one side of the carriage. The skidding yrope 10 is operated by the t rum b', such rope extending over the sheave11 at the head support and thence to the. carriage.

12 is the slack pulling rope operated from 100 the drum b2 of theengine, such rope also extending over a sheave 13 at-the head tree andthence to the carriage. The hoisting rope of the apparatus is shown at14 and carries at one en the tongs 15.

represents the head spar tree or port (not shown).

The main or carrying cable 5 is connected mth the mam cable exten- AUNiTED sTArasfPATij-T"FB-EE, j/i

sion 16 at the point 17, such extension passing over the guideblock 18at the Vhead support. y y i The skidding apparatus just described is ofa well known construction, and the operation of the same'will be readilyunderstood.

In Fig. 1, the main cable extension 16 is connected at the point 17awith a plurality of blocks and tackles D and E, each comprising arunning block and afixed lblock reeved together in the mannerhereinafter described. For the purpose of convenience we will herein-Mafter designate these blocks and tackles as heel blocks.

The block D is provided with an end loop 19, while the block E isprovided with a simllar loo 20, whereby such blocks may be detachab yconnected to any suitable anchorage, such as the stumps f. A'sstated,'the

arts D and E or the purpose of applying tension, each is provide with arope or line extending to drums mounted on the engine for this purpose.As will be seen from the drawings, the

lock D has a tension rope 21 extending to a sheave or pulley 22 at thehead tree and thence to the drum b3 of the engine, while the block E issimilarly provided with a rope 23 passing over the pulley 24 andthenceto the `drum b4 on the engine.

In Fig. 3, wehave shown a construction of engine especially adapted foruse in conjunction with the cableway'of the character heresuch indescribed. As stated, B indicates the engine as a whole, but in saidfigure the boiler,

.certain drums, and the connect-ions therefor for operating the hoistinand hauling ropes are omitted, while additional drums b3 and b4 areprovided. These drums are fast on the shafts b5 and b6 each drum havin alarge gear wheel 67 adapted to mesh wit a clutch pinion bs loose uponthe power shaft b".

61 indicates clutch members splined to the power shaft to turntherewith, but free to slide or shift lonvitu :linallyof the shaft, andeach of members engages with the adjacent clutch member 71s to turn thelatter with the shaft. Each ot the drums b3 and b* is provided with aband brake b operated by a foot-lever b12 -so that'by a plymg its brakeeither of the drums may be iieldagainst revolution as desired. One ofthe end flanges of each drum is also lequippedwith a circular rack b13adapted to be engaged by a suitable pawl b to lock the drum againstmovement.

The o eration of the apparat-us is as follows: When it is desired to loga run, the parts are assembled substantially as shown in Fig. 1, themain cable-way 5 being held taut b v tension applied to the extension 16through one of t ie heel blocks, in the present instance, that shownat'D, the tension rope 21 being drawn taut by winding upon t e drum b3of the engine. In the meantime, the

are in the form of blocks, and

running block E is slack and loose, and its tension line is Aalsonecessarily loosenedby reeling off from the drum b4. After therun hasbeen logged, it is desirable to slacken ten-v sion rope 21 to permit themain cable' to be slackened and lowered so that 1t may be un- `coupledand a second similar cable connected at t ie point 17 in place of thefirst one. This is accomplished by permitting the line 21 to slackenofi' the drum `b3,. said drum-being rej leased, and the cable in use isconsequently lowered. The second-cable is then attached and the drum -bis actuated to haul in the line 23 which 'tends to elevate the maincableand tightenor tension the heel block E. The

and secured to another stump or anchorage I op osite the next run.

n Fig. 2, Wel have shown a slightly modii ed form of device', for, inthis case, instead of employing a slngle rope forming a mam cable.extension or guy, we employ a lurality of guy ropes 16. and 16b each ofw ich` passes over the guide-sheave 1S the ends of the guys beingdetachably connected to the main cableway at the point 17 in any su1table manner. The apparatus shown 1n Fig. 2 has the same mode ofoperation as that shown in Fig. 1, and such operation, therefore,neednot be described in detail.

While we have herein shown and' described one particular embodiment ofour invention, we wish it to be understood that we do not confineourselves to all the precise details of construction herein set forth,as there may be modifications and variations in certain res erts withoutdeparting from the s irit of tie invention or sacrificing any of t eadvantages thereof.
